Properties of Sulfur Particles Formed in Biodesulfurization of Biogas [PDF]

Minerals, 2020
In the biodesulfurization (BD) process under halo-alkaline conditions, toxic hydrogen sulfide is oxidized to elemental sulfur by a mixed culture of sulfide oxidizing bacteria to clean biogas. The resulting sulfur is recovered by gravitational settling and can be used as raw material in various industries. However, if the sulfur particles do not settle,

Visualizing the invisible: class excursions to ignite children’s enthusiasm for microbes

Microbial Biotechnology, Volume 13, Issue 4, Page 844-887, July 2020., 2020
The ubiquity of microbes, their manifold activities and pervasive influence on the health of all life, local environments and the planet, necessitate an understanding of relevant microbial processes for informed, evidence‐based decision‐making at all levels of society – i.e. Microbiology Literacy.

The Surfactant Tween 80 Enhances Biodesulfurization [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT In biocatalytic conversions, substrates and products may display inhibitory or toxic effects on the biocatalyst. Rhodococcus erythropolis 1awq could further remove sulfur from hydrodesulfurized diesel oil, and the biodesulfurization was enhanced by the surfactant Tween 80.

Adsorptive Desulfurization of Organic Sulfur from Model Fuels by Active Carbon Supported Mn (II): Equilibrium, Kinetics, and Thermodynamics

International Journal of Chemical Engineering, Volume 2020, Issue 1, 2020., 2020
Mn (II)/AC adsorbents were prepared by ultrasonic impregnation. The 2 wt. % Mn/AC showed best adsorptive performance, and the optimal adsorption temperature was 313 K. Benzene, methylbenzene, and naphthalene were used to explore the adsorptive selectivity of Mn/AC, indicating that Mn could enhance the adsorptive capacity but could not improve the ...

Development and validation of a physiologically based kinetic model for starting up and operation of the biological gas desulfurization process under haloalkaline conditions

Water Research X, 2019
Hydrogen sulfide is a toxic and corrosive gas that must be removed from gaseous hydrocarbon streams prior to combustion. This paper describes a gas biodesulfurization process where sulfur-oxidizing bacteria (SOB) facilitate sulfide conversion to both ...

Bacterial Biological Factories Intended for the Desulfurization of Petroleum Products in Refineries

Fermentation, 2023
The removal of sulfur by deep hydrodesulfurization is expensive and environmentally unfriendly. Additionally, sulfur is not separated completely from heterocyclic poly-aromatic compounds. In nature, several microorganisms (Rhodococcus erythropolis IGTS8,

Assessment of the Oxidative Desulfurization of Middle Distillate Surrogate Fuels with Spectroscopic Techniques

Journal of Analytical Methods in Chemistry, Volume 2020, Issue 1, 2020., 2020
The oxidative desulfurization of five (5) model sulfur compounds and eleven (11) surrogate blends was investigated using the hydrogen peroxide (H2O2)‐acetic acid (CH3COOH) system. Consequently, extractive desulfurization was carried out using conventional solvents.

Designing recombinant Pseudomonas strains to enhance biodesulfurization [PDF]

Journal of Bacteriology, 1997
The dsz biodesulfurization cluster from Rhodococcus erythropolis IGTS8 has been engineered under the control of heterologous broad-host-range regulatory signals to alleviate the mechanism of sulfur repression, and it was stably inserted into the chromosomes of different Pseudomonas strains.

Whole-Genome and Transcriptome Sequencing-Based Characterization of Bacillus Cereus NR1 From Subtropical Marine Mangrove and Its Potential Role in Sulfur Metabolism

Frontiers in Microbiology, 2022
Sulfur, organosulfur compounds, and sulfides are essential parts of life. Microbial sulfate assimilation is among the most active and ancient metabolic activities in the sulfur cycle that operates in various ecosystems. We analyzed the molecular basis of
